The Fwooper is a magical African bird with brightly-coloured feathers, which can include orange, pink, lime green and yellow. Listening to the Fwooper's song will drive the listener insane, so each bird must be sold with a Silencing Charm placed on it. The Charm has to be reinforced monthly, and a licence is required to own one of the birds.[1]

Uric the Oddball once tried to convince the Wizards' Council that the Fwooper song was actually beneficial to a Wizard's health, and listened to it continuously for three months. His presentation did not go well, when he turned up wearing nothing but a toupee that, on closer examination, was revealed to be a deadbadger.[1]

The four colour varieties of the Fwooper are used to represent the number four, in the runic alphabet.[2]
